SPECIFICATION forming part of Letters Patent No. 545,790, datedSeptember 3, 1895.

, Application had April 2, 1895. sean No. 544,181. (No man.)

To all whom it may concern:

Be it known that 1, ENooH fR. GARRETT, a citizen of the United States,residing at Appieton Oity, in the county of St. Clair and State ofMissouri, have invented a new and useful Steamer, of which the followingis a specification.

This invention relates to an improvement in Steamers for heating orcooking feed for live-stock.

The object of the present invention is to provide a simpleand-inexpensive construction of steamer which shall be capable ofpreparing o1; steaming any desired amount of feed While the latter is inthe mixing-trough.

A further object of the invention is to construct the steaming apparatusin such manner that it may be taken apart for cleaning, storage, ortransportation. A

To this end the invention consists in providing a steamer with twoseparate and independent annular chambers and in providing the same withupper and lower communicating apertures, thus providing for a propercirculation of water; in the manner of supporting the smoke flue or pipewithin the steamer; in the manner of coupling the firebox or furnace tosaid steamer, and in certain other features and details of constructionand arrangement of parts hereinafter fully described, illustrated in thedrawings, and pointed out in the claims.

In the accompanying drawings, Figure l is a perspective view of a feedcooker or steamer constructed in accordance with my invention.

Fig. 2 is a vertical sectional view showing the manner in which theannular chambers are combined and arranged, showing also the manner inwhich the smoke due or pipe is supported in position and the steamercoupled Fig. 3 is a detail perspective view of the separable tire-box orfurnace.

Similar numerals of reference indicate corresponding parts in theseveral ligures of the drawings.

The body of the steamer comprises two separate and independent annularchambers 1 and 2. The chamber 1 is composed of a tapering cylindricalinner wall or sheet 3, decreasing in diameter toward the top, and anouter cylindrical wall or sheetl of approxi the same throughout itslength and somewhat greater than the internal diameter of the chamber 1,upon the top plate 5 ofwhich said sheet 6 rests, and said chamber 2 alsocomprises a tapering cylindrical outer Wall or sheet 7, Which surroundsthe inner wall 6 and extends down over and surrounds the inner chamber1, terminating at a point just above the bottom of said inner chamberand being united thereto, as shown at S. The diameter of the outer Wallor sheet 7 increases as it approaches the top,where it is connected byan annular plate or cap 9 with the upper end of the inner wall or sheet6. Two separate and independent Water-containing chambers are thusprovided, one overlapping the other, and the intermediate Wall 4 betweensaid chambers is provided with an upper aperture 10 at the upper end ofthe inner chamber and a lower aperture 11 at the bottom of the `outerchamber.

The smoke line or pipe 12 is preferably made tapering at its lowerendand provided with an annular flange 13, which rests upon the internalshoulder formed by the top of the inner chamber 1, and said pipe, justabove the top 9 of the chamber 2, is provided with a Vhinged door 14:,by means of which fuel is supplied to the re-boX or furnace. The furnaceconsists of a cylindrical box 15, which is provided at one side with aperforation 16 and at the opposite side with a notch or open slot 17,said perforation and notch being adapted to receive the shaft on whichthe dumpinggrate 1S is supported. Suitable radially-projecting brackets1 9 are attached to the exterior surface of the furnace-box at Ysuitableintervals, the upper edges of said brackets being in the same horizontalplane with the upper side of the grate-supporting shaft and adapted toreceive the lower edge of the steamer and to support the same relativelyto the lire-box. The grate-supporting shaft is thus held in place whenthe steamer is in position, butrnay be removed when the steamer isdetached from said fire-box. A series of pivoted loops, connected to thelower end of the chamber 1 upon the exterior wall thereof, pass beneathand engage the brackets 18 on the tire-box, thus coupling the partstogether. A hinged door 2O at one side of said tire-box provides for theremoval of the ashes and affords the necessary draft. In operation,water is introduced into the chambers l and 2 through a supply-pipe 2lextending upwardly upon the exterior of the steamer. Said supply-pipe isprovided with i a suitable funnel at its top and enters the chamber 2 atthe bottom edge thereof. Sufiicient water is introduced into the steamerto till the same up to the line of a suitable faucet 22, the purpose ofwhich is to indicate when sufficient water has been introduced' into thesteamer. Another faucet 23, located at the bottom of the inner chamber1, provides for drawing off the Water when desired. A fire having beenkindled in the furnace-y box 15, the products of combustion pass up rthrough the space within the inner chamber and thence out of the smokeflue or pipe l2. In their passage they heat the water in the chamber lto the boiling-point, when it passes out through the upper aperture 10into the; outer chamber 2, the cold water therein passing downward andthrough the lower aper-A ture 1l into the inner chamber l. By reason ofthe space at the bottom of the inner chamj ber being less than at thetop of said cham- 1, ber, the shallow body of water is adapted to 2 bemore easily heated. The steam finally escapes into the upper end of theouter chami ber 2, from whence it is conveyed, throughv a flexible hoseor pipe 24 to the desired point. The steam-pipe 24 is provided at itsend with a metallic sleeve 25, which receives a detachable steamradiator or distributor 26, made of perforate sheet metal, which isadapted to be inserted into the feed for properly directing: the steamthereto.

The feed cooker and steamer above described is simple in constructionand may be manufactured at slight cost. It is also portf able, will befound thoroughly efficient in use, and by means of the flexiblesteam-pipe the steam may be conducted to any desired point. The devicemay be used for heating water for 'f bath-rooms, also for furnishing hotwater and steam for laundry purposes, and is also well adapted for usein connection with fruit-evaporaters, te.

It will be apparent that various changes in the form, proportion, andthe minor details of construction may be resorted to without departingfrom the principle or sacrificing any of the advantages of thisinvention.

Having thus described the invention, what is claimed as new, and desiredto be secured by Letters Patent, is-

1. In a steamer for heating or cooking food for stock, the combinationwith a tapering inner chamber' surrounding the central smoke iiue andhaving its lower end contracted, of a tapering outer chamber surroundingsaid inner chamber and having its lower end also contracted, the upperand lower apertures connecting said chambers for providing forthe propercirculation of the water, a furnace located at the bottom of the innerchamber, and a steam pipe or outlet communicating with the steam spaceof the outer chamber, substantially as and for the purpose described.

2. In a steamer for preparing feed for live stock, a cylindrical andtapering inner chamber, in combination with a tapering' and cylindricalouter chamber surrounding said inner chamber and extending upwardlybeyond the upper edge thereof, the upper and lowercommunicatingapertures between said chambers, a removable smoke pipearranged within the outer chamber and resting upon the top of the innerchamber, and a detachable fire box or furnace connected to the lower endof the inner chamber, in the manner and substantially as described.

3. In a steamer for preparing feed for live stock, a tapering annularinner chamber, and a tapering annular outer chamber surrounding saidinner chamber and extending above the same, and the upper and lowercommunieating apertures between said chamber, in combination with adetachable fire box secured thereto in the manner described, adetachable smoke pipe provided with a flanged base resting upon theupper end of the inner chamber, a supply pipe communicating with thelower end of the outer chamber, and a flexible steam pipe communicatingwith the steam space at the upper end of the outer chamber,substantially as specified.

In testimony that I claim the foregoing as my own I have hereto affixedmy signature in the presence of two witnesses.

ENOCI-I R. GARRETT.
